Yea, that helps.  The errors you have are really these:

	! psql: could not fork new process for connection: Resource temporarily unavailable

and
	! psql: could not send startup packet: Broken pipe

Is anything else big running on your machine?

I looked at the OSX configuration section here:

	http://candle.pha.pa.us/main/writings/pgsql/sgml/kernel-resources.html

but didn't see anything significant.  My guess is that the parallel
nature of the regression tests are exhausting some system resource on
your machine.  Does the kernel log have anything of interest?
